IBM announced a dual-architecture mainframe processor supporting IBM and Arm platforms in future Z and LinuxONE systems.

IBM announced what it described as the first dual-architecture mainframe processor. The processor is being designed to support operating systems and applications across both IBM and Arm compute platforms.

IBM plans to use the processor in future IBM Z mainframes and LinuxONE systems. The announcement refers to a processor-design milestone rather than a currently shipping Z or LinuxONE product.

The dual-architecture description concerns support for two compute platforms within IBM’s future mainframe systems. The supplied announcement does not provide core counts, clock speeds, process technology, power consumption, pricing, or a commercial availability date.
